The closest you can get to a conversation with Jacob Wetterling about his abduction is to talk to Jared Scheierl. Scheierl was walking home from an ice skating rink in Cold Spring in January 1989 when a man who turned out to be Danny Heinrich forced him into a car, assaulted him, and let him go, uttering some chilling parting words: "If they come close to finding out who I am, I'll find you and kill you." That was nine months before Jacob's abduction. 

When Jacob Wetterling was taken, authorities launched what would turn into one of the largest searches for any missing person in the history of the United States. But that first night, law enforcement didn't cover all the basics. 

The abduction of Jacob Wetterling, which made parents more vigilant and led to the first national requirement that states track sex offenders via registries, took place before moonrise on a warm October night in 1989. 

After he disappeared nearly 27 years ago, Jacob Wetterling's remains have been found. Why did it take so long?
